LOOSE-LEAF BINDER.

Specification of Letters latent.

Patented Nov. 21, 1916.

Application filed November 4, 1913. Serial No. 799,177.

Rochester, in the county of Monroe and State of New- York, have invented a new and useful Improvement in Loose-Leaf Binders, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to loose leaf binders, and an object thereof'is to provide, in that type of binder having impaling projections with a binder member releasably engaging the upper ends of the projections, a means of connecting a hinged cover to the binding member in such a manner that a durable and compact structure is provided.

Another object of the invention is to provide transfer means which will adapt the binder for use with 'book typewriting machines and which will permit the leaves to be shifted to the platen and then disposed upon the upper cover member without being removed from the binder, provision preferably being made whereby any individual leaf may be removed without removing any of the other leaves. I v

To these and other ends the invention consists in certain parts and combinations of parts all of which will be hereinafter described and the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a vertical section through the rear portion of a binder embodying the present improvement; Fig.

a detail. view showing the hinged cover in open position on the connecting or binder member shown in Figs. 3 and 4; Fig. 7 is a side view showingthe loose leaf binder in open position with the main transfer memher in position thereon for receiving leaves to'hold the latter supported on one of the covers; Fig. 8 is a perspective view of the main transfer member; Fig.9 is a longitudinalsectional view of the connecting o1 binder member shown in Figs. 3, 4 and -5, the auxiliary transfer member being connected thereto; Fig. 10 is a side 'view of the binder with the auxiliary transfer member in place thereon; Fig. 11 is a perspective view of the auxiliary transfer member; Fig.

12 is a perspective view of one of the leaves used 1n the binder; and Fig. 13 is a side elevation showing the binder shifted from the position shown in Fig. 10 to. permit the withdrawal of the leaves. i a

In the illustrated embodiment, a: and indicate the two connecting 'or binder members, the memberm comprising a metal bar 1 with impaling projections 2 extending from oneside thereof and preferably two in number. These impaling projections preferably are elliptical in cross section and have hooked or shouldered ends 3 for engagement by a suitable retaining means or substantiallyU-shape or channel shape in cross section with their channeled portions disposed toward each other to form a casing between them. Within this casing or binder member y, a locking means is arranged for cooperation with the impaling means and preferably comprises a slide bar 6 having a finger piece 7 at one end for the manipulation thereof. This bar may be pressed in one direction by a coil spring 8 in order to engage the shouldered ends 3 of the impaling projections 2, the casing being provided with two suitable openings 9 through which the ends of the impaling projections are passed so as to be engaged by the locking bar 6.

The two binder members are preferably connected by a back piece 10 through the means of a hinged connection 11 formed by the leather which covers the back piece and the binder members. Cover members are also attached to the binding pieces, one of said cover members comprising two sheets of card board 12 having a sheet of metal 13 doubled on itself and arranged betweensaid card boards near one edge, the bend .in the doubled sheet metal piece 13 being notched and forming sleeves for the reception of a pivot pin 14. Straps 15,

doubled on themselves, are riveted at their ends at 16 to the bar 1, the doubled portions of said straps also fitting around the bar or pivot rod 14 and forming a hinge for this cover member.

The other cover member may be formed by two cardboard sheets 12 which have a sheet metal strip 17 between them. To this sheet metal strip, straps 18 are secured, said straps being doubled upon themselves and projecting from one side of the plate 17. These straps 18 turn on a pivoted rod 19 arranged within the binder member y, the casing of the latter being'cut away to permit the straps to extend into the casing. To support this pivot rod in one corner of the casing or binder member y, the member 5 has one of its side walls cut to provide an inwardly extending tongue 20 while the member 4 has its top wall cut to provide a downwardly-extending tongue 21, the rod 19 being confined in one corner of the casing by the tongues 20 and 21, as will be seen by referring to Figs. 3, 4, and 5. To the end that the uppermost cover member may swing to an extreme open position, such as shown in Fig. 6, the straps 18 are bent at 22 so the loop 23 of said strap is in a plane to one side of the center plane of the cover member, and .the top surface of the cover member in proximity to the hinge may be beveled at 24.

With the binder there may be employed a main transfer member which preferably comprises a plate or strip 25 having transfer projections or pins 26 extending from one side thereof. The transfer pins or projections are adapted to pass through openings 27 in the leaves 28 at the same time that the impaling pins 2 are extended through the openings or slots 29 in the same sheet, the upper ends of the impaling pins 2 extending through openings 30 in the transfer bar 25 in order to engage with the locking means of the binder member y. This transfer member is used for removing any number of sheets from the impaling projections or for placing the sheets upon the impaling projections without destroying the alinement of the openings in the sheets, The transfer member may also be employed for receiving the sheets as they are removed one by one from the impaling projections 2 and to this end means is provided for supporting the transfer member with its transfer projections upright in such a position that, when the leaves are fitted to the transfer member, they will be supported by the upper cover member. This is accomplished by providing the transfer plate 25 with laterally-extending projections 31 which are formed with shoulders 32 and are adapted to interlock with the binder member y, the latter, for this purpose, being provided with openings 33 through which the projections 31 may be passed in order that the shoulders 32 may be engaged by the locking member or bar 6, which thus serves the dual function of holding the binding members a: and y together and, at the same time, of supporting the transfer member in an upright position.

'An auxiliary transfer device may be employed with the binder for the purpose of receiving the leaves from the impaling projection without detaching the leaves from the binder. This transfer means is especially designed for adapting the binder for use with book typewriting machines. It permits the leaves to be elevated, one at a time, to the position shown in dotted lines in Fig. 10 in order that the platen of the typewriting machine may be disposed under the same, the leaves being provided with openings 34 adapted to be fitted over the positioning projections on the platen of the book typewriting machine. After the leaf has been used, it may be shifted to an outof-the-Way position while being held within the binder. The construction of this auxiliary transfer member is such that it permits any one or more leaves to be removed from the binder without removing the remaining leaves. This auxiliary device is shown in perspective in Fig. 11 and preferably comprises two loops or goose necks each consisting of an upright or vertical portion 35 having its lower end free or pointed at 36 so as-to readily be received within the alined openings 27 of a number of leaves. From the upper end of this upright portion, a portion 37 extends downwardly and outwardly to connect with an upright portion 38, the upright portion 38 of the two loop members being connected by a horizontal portion 39 which serves to hold the two loop members in parallel relation.

lVith the purpose in view of securing the auxiliary transfer member to the binder, the.

transfer member may be provided with means for connecting with the binder member 3] so that the leaves, while surrounding the upright portions 38, will rest upon the upper cover member as shown in Fig. 10. In this instance, this securing means comprises two projections 40 having shoulders 41 to be engaged by the locking member 6 after the projections 40 have been passed through the openings 33 as will be seen by referring to Fig. 9 of the drawings. The auxiliary transfer member is held firmly on the binder by means of two oppositely extending springs 42, one of which cooperates with the back piece 10 and the other of which cooperates with the upper cover member when the parts are in the position shown in Fig. 10. The springs 42 are made by providing a rectangular frame of wire, the opposite sides of which extend through the removed from the binder as will be seen by referring to Fig. 13.

In the use of the binder, the leaves 28 are introduced upon the impaling projections 2 and the transfer member25 has its transfer projections fitted in the openings 27 where they are held by the engagement of the up. per binder member 3 with the upper ends of the impaling posts 2. Shouldit be desired to remove a leaf, the locking-bar 6 is moved to free the impaling projections and the projections 31 of the transfer member. The upper cover member may now be thrown to the position shown in Fig. 7, the transfer member remaining in the openings 27. This member is now lifted with all those leaves above the leaf which it is desired to remove, thus making it possible to withdraw the desired leaf, and, at the same time, holding, with their openings alined, the other leaves that have been withdrawn from the impaling projections.

If, instead of removing a single leaf, it is desired to remove the sheets one at a time, the main transfer member may be connected to the binder member 3 as shown in Fig. 7 so that each leaf, as it is removed from the impaling post 2, maybe deposited on the transfer projections 26 to rest upon the upper cover member. After the desired number of leaves have been deposited on the transfer member, said leaves and the transfer member are disconnected from the binder member y by shifting the locking member 6, the leaves then being fitted to the impaling projections 2.

If it be desired to use the binder on a book typewriting machine, the transfer member 25 is removed entirely and the auxiliary transfer member shown in Fig. 11 is connected to the binder, as shown in Fig. 10. The lower binder member as is attached to the usual projections of typewriting machines and to this end is provided on its outer face with openings 43 for the recep tion of such projections. The platen will then operate above the leaves on the impaling posts and the leaves are elevated one at a time on the upright portions 35 so as to rest upon the platen. After each leaf has been used, it is carried by way of the inclined portions 37 to the upright portions 38 where it rests until the leaves on the upright portions 38 are carried back to the upright portions 35 and onto the impaling projecing upwardly on the auxiliary. transfer member, causing the withdrawal of the upi right portions 35 of the openings 27 and permitting the leaves to be removed from the impaling posts as shown in Fig. 13.

A loose leaf binder constructed in accordance with this invention provides a new hinged connection between the cover member and the binder member which carries the locking means. The pivot bar of the hinge is supported in one corner of the casing which incloses the locking means so that the operation of the locking means is not interfered with. The straps of the hinge and the cooperating parts are formed so that the upper cover member may be opened to an extreme position while the binder members are connected together.

The auxiliary transfer member is of novel construction. It permits the elevation of the leaves above the impaling posts to allow the platen of a book typewriter to be positioned below such leaves. The leaves are then movable to a position where they may be supported by the upper cover member in a position to be readily transferred to the impaling projections without removal from 'the binder. The auxiliary member is so connected to the binder that individual leaves may be removed without removing any of the other leaves.
